OSHA 1926.1431: rigging hardware must be capable of supporting at least _____times the maximum intended load applied or transmitted to that component.

• A. 3
• B. 5
• C. 4
• D. 6

Answer: (B)

Rigging hardware is required to have a built-in safety margin that accounts for real-world lifting conditions. OSHA specifies that it must be capable of withstanding at least five times the maximum load that could be applied or transmitted to that component. This five-to-one factor provides a cushion for dynamic or shock loads, misalignment, angle loading, wear, and other uncertainties that can occur during a lift, reducing the risk of sudden failure and dropped loads.

The “maximum intended load” means the worst-case load the hardware could experience in the actual lift, including any force transmitted through attachments and any dynamic effects. By selecting hardware rated for five times that load, you ensure the equipment can remain safe even if the lift is not perfectly balanced, if a line shifts, or if a load experiences a sudden surge.

For example, if the planned lift could reach 2,000 pounds, you would choose hardware rated for at least 10,000 pounds of capacity to meet this requirement. The other options don’t meet the mandated minimum safety factor.
